3 years, 8 months ago3 years, 8 months ago@chase-grim so looking at macrostrat.org it looks like that area is Ordovician-Silurian in age meaning it not likely a plant since we don’t see a lot of land plants until the Devonian. My guess would be an animal (or animal colony) like graptolite, bryozoan or even some sort of echinoderm since they too can have branching appendages. I’m going to…[Read more]

4 years, 6 months ago4 years, 6 months ago@jkallmeyer can you help with this trilobite ID?

@sadie-mills Sorry, not from this photo. Needs a closer sharp photo but it looks to be only the thorax from this photo which would make it impossible to ID.

@jkallmeyer any ideas?

4 years, 8 months ago4 years, 8 months agoHi, @jkallmeyer – really nice specimen. The class is Craniata and order is Craniida: https://paleobiodb.org/classic/basicTaxonInfo?taxon_no=26536
If you could update the classification and include in the notes what the scale bar represents I can mark the specimen as research grade.
Thanks, Jen -

Could you include what the scale bar represents in the notes section?
Do you have another image of the oral surface? Maybe not incredibly necessary since it’s identifiable otherwise but that is a highly diagnostic area.
Talk to you soon,

If you could include what the scale bar represents in the notes that would be great.
The classification should be Class Rhynchonellata > Order Atrypida > Family Anazygidae https://paleobiodb.org/classic/basicTaxonInfo?taxon_no=307372Talk to you soon,

4 years, 8 months ago4 years, 8 months agoHi, @jkallmeyer, The class should be Rhynchonellata. The PBDB also suggests family Glyptorthidae: https://paleobiodb.org/classic/basicTaxonInfo?taxon_no=307159
It seems like the family Dolerorthidae may be a Silurian-Devonian group rather than Ordovician. If you remember where you referenced the family I can do some more research.
Talk to you soon,

4 years, 8 months ago4 years, 8 months agoHi, @jkallmeyer – for your reference, I think the class is Strophomenata and Leptaenidae is a subfamily so the family is Rafinesquinidae.
Here is the PBDB record, which doesn’t show subfamily but if you type it into the search engine it still pops up. I’m not sure why they exclude it from the string on the species…[Read more] -

4 years, 8 months ago4 years, 8 months agoHi, @jkallmeyer I have done some research on how other collections include trace fossil data and it seems like we will include Kingdom Animalia > Phylum Ichnofossil > include ichnogenus and species in the genus and species boxes — and if you want to include trace maker information it can be put in the field notes section.
Does that seem…[Read more]

That sounds right although I did not include the actual trace fossil taxonomy which I probably do not know. I included the taxonomy of the possible trace maker. Poor form… but my original purpose wasn’t to do a proper museum label but rather to show people what a trace fossil from a given critter looked like.

That’s why I’m around, to help with figuring out the correct information! I would think this would be Diplichnites (generic assignment) – very common for arthropod trackways.

I go by Osgood’s work wherein he discusses Cincinnatian arthropod trackways under different genera stating, “there is considerable doubt as to the true affinities of the commonly mentioned genera of supposed trilobite tracks… Diplichnites” (p352, 355). So each of the trackways I have submitted would have different ichnogenera and none would be…[Read more]

I don’t have access to Osgood’s book at this moment. I was taught that it’s bad form to name the track after the tracemaker because many different animals can make similar tracks.
If you want to follow Osgood, that is fine just include the year of the publication in the notes so someone else can follow in your steps. As you currently have it,…[Read more]
